REEL.

Patented May 8, 1317.

Application 'filed June 29, 1915, Serial No. 37,113. Renewed April 9,1917. Serial No. 160.896.

To all whom it may concern:

Be it known that I, Enwnv V. LAWRENCE, acitizen of the United States,residing at Brookfield, in the county of lVorcester and State ofMassachusetts have invented certain no and useful Improvements in Reels;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to reels and more particularly to that type usedfor supporting a roll of scaling tape from which lengths of sealing tapemay be drawn for sealing pack ages or the like.

It has for an object to provide an 1111- proved form for mounting a reeland a ten-- sion controlling device for retarding the withdrawal of thetape from the reel.

A further object of this invention is a provision of a return mechanismfor rewind-ing the end of the tape when the end of said tape is releasedafter having been drawn from the reel.

A further object of this invention is a pro vision of a ratchetmechanism for releasing the action of the roll of tape and this ratchetmechanism being of such design as to have one portion thereofsufliciently damaged when the roll of tape supported thereby is consumedto prevent rewinding of another grade of tape upon that portion thereof,which serves as one of the members of the ratchet mechanism.

Further objects will be apparent from the following specification,appended claims and drawings thereof, in which Figure 1 is a sideelevation of the reel showing a cover member removed, and

Fig. 2 is a vertical sectional view through the machine at right anglesto the plane shown in Fig. 1.

This reel will be used in conjunction with a hand sealing machine onwhich the roll of sealing tape is to be supported by the mechanismcomprising this reel. As the sealing machine will be used upon storecounters and the like and in view thereof the use of the machine willcover large areas of the counter so to accommodate the range the reelmay be supported by a trolley which has movement in directions mostconvenient for the use of the sealing machine.

Referring to the drawings, 10 indicates rods which form a track uponwhich the wheels 11 rotate and these wheels are supported by the axles12 of a carriage 13 from which an eye 1% depends to receive an eye 15 towhich the reel is swiveled. The pin 16 which passes through the enlargedpart of the eye 15 supports the tongues 17 and 18 which are formed onthe sides 19 and 20. A spindle 21 passes through these sides andsupports a hub 22 of relatively large proportions so as to render thesame impractical for grades of sealing tape other than those for whichthe hub is intended. The spindle 21 is threaded as at 23 to receive theadjusting nut 24 to facilitate in adjusting the tension upon the hub orspool 22 as by the spring 25 and the opposite end of this spindle isthreaded as at 4 1 for engagement in the block 45 supported by the cover26 as by the screws 27. The

cover 26 is attached to the side 20 as by the screws or other fasteningmeans 28 and as will be seen, the cover 26 indirectly supports the endof the spindle 21 to permit the dev sired compression being establishedbetween the sides 19 and 20 on the spool 22.

A head 29 is rotatably mounted upon the spindle 21 and this head isrecessed as at 30 to receive the pawl 31 which is normally held inextended position as by the spring 32. The pawl 31 is adapted to engageone or another of a series of notches 33 formed in one of the ends ofthe spool 22 which are preferably made of wood. The head 29 is connectedas at 34: to one end of the spiral spring 35 which is wound about saidhead and has its other ends supported as at 36 by one of the screws 28.

hen a roll of sealing tape is placed in the machine having the spool 22supported between the sides 19 and 20 upon the spindle 21, the end ofthe tape may be withdrawn from the reel at which time, through thenotches 33 and pawl 31 the head 29 is rotated to exert a tension on thespring 35. When this tension reaches a maximum, the 1% pawl 31 yieldsand allows the spool 32 to rotate without imparting any movement to thehead 29. As soon as the end of the tape has been released, the spring 35in its energized state imparts reverse motion to the head 29 whichthrough its connection with the spool 22 serves to rewind the tape. Thespool 22 will preferably be made of wood and the fibers thereof willsustain the action of the pawl 31 until the paper has been consumed fromthe spool, but by the time the first reel of paper is consumed the spoolis so damaged by the pawl 81 that it cannot be used for the second rollof tape. Also, the spool 22 will preferably be made any odd size so thatit cannot be inserted in any standard roll of tape to permit thesubstitution of an inferior grade.

It is thought that the operation of this device is understood in view ofthe foregoing and that the benefits to be derived from its movablesuspension will be appreciated. Also it is apparent that variousmodifications may be made within the scope of this invention withoutdeparting from the spirit thereof, as the drawings submitted are forillustrative purposes only.

Having thus described my invention, 1 claim 1. A reel of the classdescribed comprising side plates, a spindle carried by said side plates,a spool frictionally held between said side plates, a head rotatablycarried by said spindle, a pawl yieldably carried by said head engagingsaid spool, a spring connecting said head and one side member, and meansfor regulating the frictional contact of said side plates, spool andhead.

2. A reel of the class described comprising side plates, a spindlesupported by said side plates, a removable cover member supported by oneof said side plates, one end of Copies said spindle being supported bysaid cover, an adjusting nut and spring supported by the opposite end ofsaid spindle, a spool frictionally held between said side plates aboutsaid spindle, a ratchet face formed in said spool, a head rotatable onsaid spindle, a pawl yieldably supported by said head adapted tocooperate with said ratchet face and a spring connecting said rotatablehead and said frame.

3. A reel of the class described comprising side plates, a spindlecarried by said side plates, a spool rotatable on said spindle, a headrotatable on said spindle, a pawl yieldably carried by said headcontacting with said; spool, said spool and head being relativelymovable with each other, a spring connecting said head and one of saidside plates, said spool having a series of notches formed thereinconcentric with the line formed by said pawl in its rotation, and saidpawl having a damaging effect on the recess formed in said spool withwhich it engages when said spool is rotated independently of said headto limit the life of usage of said spool.

In testimony whereof I affix my signature in-presence of two witnesses.
